Short circuit results in current (usually maximum current) and zero voltage so is zero power output.

Short circuit typically is considered loaded. The load is the coil itself because there is current flowing in the coil and the coil has resistance, so IsquaredR power loss in the coil, but zero power to any external load due to the shorted terminals.

Whenever I've read about the speed up under load or watched video demonstrations, the starting condition was no-load meaning coil terminals open circuit. Then the loaded condition had a resistance (often light bulb) across the coil terminals or in some cases, the loaded condition was simply a short circuit across the coil terminals.

How am I mistaken here?


Nobody said you're mistaken on this one point there but you like to wiggle around with your answers.

I'll ask something else...

What happens when you short a generator that is holding up to the laws you believe in?

A simple answer without the slippery talk is preferred.

And why does a generator do what it does when you short the output?
